IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 163,563, dated May 18,1875 application filed January 20, 1875.

To all whom it may concern:

Be it known that I, JOHN P. ZELLER, of South Bend, in the county of St.Joseph and in the State of Indiana, have invented certain new and usefulImprovements in Flows; and

do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon, making a part of thisspecification.

The nature of my invention consists in the construction of a plow pointand colter so that either may be detached independently of the other, aswill be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawings, in.which- Flgure l is aperspective view of a plow embodyln g my invention.Fig. 2 is a similar View w th the colter detached. Fig. 3 is a similarview with the plow-point detached. Fig. 4 is a side elevation of theplow.

A represents a plow-standard with land-side Band mold-board O. D is theplow point and share, and E is the colter. The plow-point D isconstructed, as shown, to fit on the lower part of the standard againstthe lower edge of the mold-board, and is fastened by a single bolt, a,passing through the standard. At the rear end of the plow-point is alug, b, projectlng up under and against the lower rear corner of themold-board. The point is further constructed so as to cover the edges ofthe standard A and'land-side B at the lower front part, forming a smoothjoint with the landside. The colter E is constructed to fit on top ofthe plow-point against the front edge of the mold-board, covering theedge thereof, as well as the edge of the standard, and part of the edgeof the land-side. On the land-side side the colter E is provided with aprojecting lip or wing, G, which overlaps the standard, and the colteris fastened by a bolt, d, passing through the mold-board, standard, andwing, as shown.

By this construction either the point or colter may be removedindependently of the other, for the purpose of sharpening, or, if wornout, for replacing With a new one.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

In a plow, the combination of the plow-point D, provided with lug b, andthe colter E, provided with the wing G, the point and colter beingconstructed, as described, of separate pieces, and detachableindependently of each other, substantially as herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this18th day of December, 1874.
